Comparative study on the hydrographical status in the lentic and lotic ecosystems

The objective of this study is to assess the hydrography in the lentic and lotic ecosystems. According to this study, the Water Quality Index of lentic ecosystem is highest in the Kukkarahalli lake (106.32), followed by Karanji lake (97.42), Varuna lake (95.73) and lowest in the Kamana lake (94.62). The Water Quality Index of lotic ecosystem (Kavery river) is highest in the Sangama (99.33), followed by Snanghat (96.40), Chandravana (93.05) and lowest in the Paschimavahini (90.48). So, the Water Quality Index of lentic ecosystem is higher than the lotic ecosystem in general. This indicates that, the water quality of standing water is deteriorated more than the running water.
